Valid for Submission
E00.9 is a billable diagnosis code used to specify a medical diagnosis of congenital iodine-deficiency syndrome, unspecified. The code E00.9 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code E00.9 might also be used to specify conditions or terms like congenital hypothyroidism due to iodine deficiency, congenital iodine deficiency syndrome, endemic cretinism, hypothyroidism due to defect in thyroid hormone synthesis, primary hypothyroidism , sporadic cretinism, etc.
Unspecified diagnosis codes like E00.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Inclusion TermsInclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Congenital iodine-deficiency hypothyroidism NOS
- Endemic cretinism NOS
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code E00.9 are found in the index:
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

Diagnostic Related Groups - MS-DRG Mapping
|MS-DRG||MS-DRG Title||MCD||Relative Weight|
|643||ENDOCRINE DISORDERS WITH MCC||10||1.6633|
|644||ENDOCRINE DISORDERS WITH CC||10||1.0183|
|645||ENDOCRINE DISORDERS WITHOUT CC/MCC||10||0.7678|
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert E00.9 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code E00.9 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Your thyroid is a butterfly-shaped gland in your neck, just above your collarbone. It is one of your endocrine glands, which make hormones. Thyroid hormones control the rate of many activities in your body. These include how fast you burn calories and how fast your heart beats. All of these activities are your body's metabolism.
Thyroid problems include
- Goiter - enlargement of the thyroid gland
- Hyperthyroidism - when your thyroid gland makes more thyroid hormones than your body needs
- Hypothyroidism - when your thyroid gland does not make enough thyroid hormones
- Thyroid cancer
- Thyroid nodules - lumps in the thyroid gland
- Thyroiditis - swelling of the thyroid
To diagnose thyroid diseases, doctors use a medical history, physical exam, and thyroid tests. They sometimes also use a biopsy. Treatment depends on the problem, but may include medicines, radioiodine therapy, or thyroid surgery.
